Deinstallation of old Process Simulate Versions

Hello everybody,I have an issue here. I am trying to switch the version from 13.0.0 to 13.0.1 via the Version Selector, but receive the error that no oracle client is installed.I just want to use the standalone version, so I tried to reinstall the 13.0.1 Version, but the setup is not working, claiming that it is not the currently selected version and I should change it in the version selector. Do you have any suggestions?
